List of knot terminology
This page explains commonly used terms related to knots.
A bend is a knot used to join two lengths of rope.
A bight has two meanings in knotting. It can mean either any central part of a rope (between the standing end and the working end) or an arc in a rope that is at least as wide as a semicircle. In either case, a bight is a length of rope that does not cross itself. Knots that can be tied without use of the working end are called knots on the bight.
Binding knots are knots that either constrict a single object or hold two objects snugly together. Whippings, seizings and lashings serve a similar purpose to binding knots, but contain too many wraps to be properly called a knot. In binding knots, the ends of rope are either joined together or tucked under the turns of the knot.
Another term for the working end.
A knot that has capsized has deformed into a different structure. Although capsizing is sometimes the result of incorrect tying or misuse, it can also be done purposefully in certain cases to strengthen the knot (see the carrick bend) or to untie a seized knot which would otherwise be difficult to release (see reef knot).
A decorative knot is any aesthetically pleasing knot. Although it is not necessarily the case, most decorative knots also have practical applications or were derived from other well-known knots. Decorative knotting is one of the oldest and most widely distributed folk art.
Knot dressing is the process of arranging a knot in such a way as to improve its performance. Crossing or uncrossing the rope in a specific way, depending on the knot, can increase the knot's strength as well as reduce its jamming potential.
"Flaking" or "Faking" also means to lay a rope on a surface ready to use or to run out quickly without tangles 
A friction hitch is a knot that attaches one rope to another in a way that allows the knot's position to easily be adjusted. Sometimes friction hitches are called slide-and-grip knots. They are often used in climbing applications.
A hitch is a knot that attaches a rope to some object, often a ring, rail, spar, or post.
A jamming knot is any knot that becomes very difficult to untie after use. Knots that are resistant to jamming are called non-jamming knots.
A lashing is an arrangement of rope used to secure two or more items together in a rigid manner. Common uses include the joining scaffolding poles and the securing of sailing masts. The square lashing, diagonal lashing, and shear lashing are well-known lashings used to bind poles perpendicularly, diagonally, and in parallel, respectively.
In reference to knots, loop may refer to:
- One of the fundamental structures used to tie knots. Specifically, it is a U-form narrower than a bight.
- A type of knot used to create a closed circle in a line.
A loop is one of the fundamental structures used to tie knots. It is a full circle formed by passing the working end of a rope over itself. When the legs of a closed loop are crossed to form a loop, the rope has taken a turn.
A loop knot is the type of knot that forms a fixed loop. It is created either when the end of a rope is fastened to its own standing part or when a loop in the bight of a rope is knotted. Unlike a hitch, a loop knot creates a fixed loop in a rope that maintains its structure regardless of whether or not it is fastened to an object. In other words, a loop knot can be removed from an object without losing its shape.
A noose can refer to any sliding loop in which the loop tightens when pulled.
Setting a knot is the process of tightening it. Improper setting can cause certain knots to underperform.
Small-stuff is a nautical and knot-tying term for thin string or twine, as opposed to the thick, heavy ropes that are more often used in sailing. It is commonly used in a whipping to bind the ends of ropes to prevent fraying.
Historically, the term referred to cordage less than one inch in circumference. Much of the small-stuff onboard ships, especially that used for decorative or fancy ropework, was made by the sailors themselves reusing materials unlaid from old and leftover pieces of larger rope and cable.
Splicing is a method of joining two ropes done by untwisting and then re-weaving the rope's strands.
A turn is one round of rope on a pin or cleat, or one round of a coil.
A whipping is a binding knot tied around the end of a rope to prevent the rope from unraveling.
